Use the left/right arrow keys to move the spaceship. Press the space bar to shoot a laser (which is only represented by two lines). Use the laser to hit incoming asteroids. If an asteroid is flashing, that means it has been defeated by the laser. Avoid asteroids that aren't flashing, or else you'll lose a life. You have 5 lives. For every 20 asteroids you destroy, your pass a level! There's a maximum of 9 levels.
So, I attempted to turn the classic Asteroids game into an LCD game. The final result was BAD, but I'm gonna share it anyway. Credit to Atari for original Asteroids
